1. l-Cysteine was fed to larvae carrying both a suppressor-erupt and a suppressor-tumor system, to test its effect in combination with x-ray treatments and with supplementary l-tryptophan in the diet. Cysteine itself had no effect on erupt eyes or on the incidence of melanotic tumors. 2. Fed before or after x-ray treatment, cysteine greatly reduced the radiation effect which blocks the action of the suppressor genes and thus engenders both tumors and erupt eyes. Cysteine was more effective in… Expand

Influence of tryptophan and related compounds upon the action of a specific gene and the induction of melanotic tumours inDrosophila Melanogaster
The results obtained with tryptophan, when compared with those obtained with X-rays, oxygen and hydrogen peroxide, suggest the operation of a similar mechanism in these cases, possibly centred on the peroxidative conversion of tryptophile to formylkynurenine. Expand
Effect of beta-mercaptoethylamine (MEA) on the radio-sensitivity of the male cockroach, Periplaneta americana (L.).
In the cockroach, the radioprotective action of certain alimentary substances such as vegetable oils and cabbage which have been reported to show protective action in mammals prompted examination of the effectiveness of cysteamine in this insect when administered by mouth or injected. Expand
Chemical Protection against X-Ray Damage to Chromosomes.
These and other chemical compounds are discussed as protective agents against chromosome damage by X-rays. Expand

It is suggested that tumorigenesis in adult houseflies may serve as a useful model system for the study of several aspects of insect physiology, notably nutritional balance and imbalance, mechanisms controlling the tyrosine/tyrosinase system in the blood and tissues of insects, factors influencing the darkening of the adult cuticle, ageing, pathology, and population control of insects by nutritional methods.

This chapter examines the reactions of carcinogens with sulfhydryl group (SH) groups in vivo and in vitro and discusses the de novo synthesis of glutathione and certain SH containing acid-soluble materials during the SH-SS cycle. Expand
Mechanisms of suppression.
The purpose of this chapter is to describe systems that seem to be informative and/or illustrative of types, of suppressor activity, and highlights that suppressor analysis can yield insight into arrays of problems, not readily subject to more classic genetic experimentation. Expand
